Disc Magnets Definition
A neodymium disc magnet is a round, flat magnet made from NdFeB (Neodymium Iron Boron), one of the strongest permanent magnetic materials available.
Disc magnets are typically defined by:
- Diameter
- Thickness
- Magnet grade
- Coating type
- Magnetization direction
They are widely used in electronics, motors, sensors, medical devices, and industrial assemblies.
Why Choose Disc Magnets?
The disc shape offers several advantages:
- Strong pull force relative to size
- Compact and space-saving design
- Easy integration into round housings
- Smooth appearance for consumer products
- Efficient surface contact area
- Suitable for automation assemblies
Common Sizes Available
We supply custom and standard sizes such as:
- 5 mm x 2 mm
- 10 mm x 3 mm
- 15 mm x 5 mm
- 20 mm x 10 mm
